The brandnew P&O Arvia is equipped by an impressive Glass Dome above the Panorama Deck 18.
This Sky Dome maximize time in the caribbean sunshine, the Arvia will visit. By day the roof covers a relaxed pool area with entertainment including live music and spectacular shows by night.
The marine glazing specialist Brombach + Gess developed and delivered the retractable glass roof which consists of two sliding elements and a fore and an aft non-movable part.
With an overall length of 43m, a width of 34m and a height above the baseline of 62m, the roof adorns the Arvia as an impressive highlight.
The roof structure is a grid construction with arches from starboard to portside and longitudinal beams made of welded rectangular hollow profiles.
The material of the roof structure is made of steel. The total weight of the roof has about 156 tonnes.
In order to keep the temperatures under the roof at a moderate level, the roof is equipped with high durable solar control laminated safety glass. The glasses are glued direct on the steel structure, with sealing between the glass panes. Thus the surface of the roof is flat with no upstands that could accumulate residues.This makes it easy to clean the roof.
The opening and closing process of the roof is driven by motorized electrically worm gears and chains. The running speed is 1m/min. This allows an opening and closing time of the roof within 10 minutes.
The two movable roof parts are connected with chains to two electonically synchonized geared motors. The gears are self locking, so that the movable parts can be stopped and hold safely in each position.
Pneumatic inflatable gaskets between the non-movable and the movable sections ensure that the entire roof is sealed in the closed position. The actuation is part of the automatic opening and closing procedure.
